This causes the pump to work harder on each startup and can lead to pressure tank problems and premature pump wear. A check valve holds that water column in place. If the water column drains away so does the pressure in the house causing the pressure switch to turn back on and making the pump cycle on and off repeatedly.\u003c\/p\u003e","brand":"Water Well \u0026 Septic Supply","offers":[{"title":"Default Title","offer_id":43752492105862,"sku":"SIM-503SB","price":67.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/4217\/6390\/files\/1check.avif?v=1774835982","url":"https:\/\/waterwellandsepticsupply.com\/products\/simmons-1-silicon-bronze-check-valve-503sb-lead-free","provider":"Water Well \u0026 Septic Supply","version":"1.0","type":"link"}
